Early identification and diagnosis in autism spectrum disorders in young children and infants: How early is too early? / Johnny L. MATSON in Research in Autism Spectrum Disorders, 2-1 (January/March 2008)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 2-1 (January/March 2008) . - p.75-84 Titre : Early identification and diagnosis in autism spectrum disorders in young children and infants: How early is too early? Type de document : Texte imprimé et/ou numérique Auteurs : Johnny L. MATSON, Auteur ; Jonathan WILKINS, Auteur ; Melissa L. GONZALES, Auteur Année de publication : 2008 Article en page(s) : p.75-84 Langues : Anglais (eng) Mots-clés : Early-identification Diagnosis Autism-spectrum-disorders Index. décimale : PER Périodiques Résumé : An area of research with autism spectrum disorders (ASD), which has received a considerable amount of attention recently is early diagnosis. This phenomenon is due largely to encouraging results from intensive intervention programs for children at very young ages. While five types of ASD exist, efforts in this area have focused almost exclusively on autism. To date, the primary methods of identification have been evidence-based assessment scales using established criteria for differential diagnosis and cognitive/developmental descriptive studies, which attempt to tease out behavior patterns of infants who later evince ASD from their normally developing counterparts. A third focus, which is in early development, involves genetic studies aimed at establishing biological links. However, at present such procedures are not viable for diagnosis. Opinions are rendered on the earliest age at which children can be reliably diagnosed at present, and a review of practical considerations is provided. Future challenges and directions in ASD identification and diagnosis are discussed.

Norms and cut off scores for the autism spectrum disorders diagnosis for adults (ASD-DA) with intellectual disability / Johnny L. MATSON in Research in Autism Spectrum Disorders, 1-4 (October/December 2007)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 1-4 (October/December 2007) . - p.330-338 Titre : Norms and cut off scores for the autism spectrum disorders diagnosis for adults (ASD-DA) with intellectual disability Type de document : Texte imprimé et/ou numérique Auteurs : Johnny L. MATSON, Auteur ; Jonathan WILKINS, Auteur ; Kimberly R. SMITH, Auteur ; Melissa L. GONZALES, Auteur ; Jessica A. BOISJOLI, Auteur Année de publication : 2007 Article en page(s) : p.330-338 Langues : Anglais (eng) Mots-clés : Norms Autism-battery Test Comorbid Behavior-problems Index. décimale : PER Périodiques Résumé : Establishing the cut-off scores for Autism Spectrum Disorder-Diagnostic (ASD-DA) scale for adults with intellectual disability (ID) and autism or PDD-NOS was the primary goal of this investigation. The aim of Study 1 was to determine if the ASD-DA was able to differentiate between adults with ID with and without an autism spectrum disorder, and to determine a total score cut-off for this purpose. The aim of Study 2 was to determine if the ASD-DA was able to differentiate between autism and PDD-NOS in this population. Sensitivity, specificity, and receiver operating characteristics (ROC) were computed for potential cut-off scores and were found to be acceptable. The implications of these data for diagnosing ASD in adults with ID are discussed.

Reliability of the Autism Spectrum Disorder-Diagnostic For Children (ASD-DC) / Johnny L. MATSON in Research in Autism Spectrum Disorders, 2-3 (July / September 2008)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 2-3 (July / September 2008) . - p.533-545 Titre : Reliability of the Autism Spectrum Disorder-Diagnostic For Children (ASD-DC) Type de document : Texte imprimé et/ou numérique Auteurs : Johnny L. MATSON, Auteur ; Jonathan WILKINS, Auteur ; Melissa L. GONZALES, Auteur ; Tessa T. RIVET, Auteur Année de publication : 2008 Article en page(s) : p.533-545 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The reliability of a new scale to assess Autistic Disorder, Pervasive Developmental Disorder, Not Otherwise Specified (PDD-NOS), and Asperger's Disorder in children was examined. Parents or other caregivers rated symptoms of 207 children between 2 and 16 years of age. The scale, which had 40 items in the final version, correlated highly with DSM-IV-TR and ICD-10 criteria and proved to have good inter-rater reliability and, excellent test–retest, and internal consistency reliability. These data are considered to have clinical utility given the need to establish data-based distinctions between these three subtypes of ASD. Furthermore, the measure is part of a more extensive battery measuring comorbid psychopathology and challenging behaviors. Implications for future research of this comprehensive assessment battery are discussed.
